Discover assets

NetBackup Snapshot Manager for Data Center discovers all the NFS exports, SMB shares, and their snapshots along with some of their directory metadata from all the Access Zones the user has privileges to access or view. By default, a DELL PowerScale cluster has a Single access zone known as the System Access Zone and unless you have additional Access Zones, all the NFS export and SMB Shares are in this default Access Zone. The multiple access zone can be mapped to the same or different Groupnet (Groupnet -> Subnet -> Pool). During discovery, the Snapshot Manager also associates the relevant SmartConnect of a pool to its NFS export or SMB share.

NetBackup Snapshot Manager for Data Center also discovers all the nested NFS exports and SMB shares irrespective of the depth at which they are created. Mentioned below are a few examples of nested shares discovered by Snapshot Manager: ["/ifs/test_fs1", "/ifs/test_fs1/test_fs2", "/ifs/test_fs1/test_data/test_fs3", "/ifs/smb_03/test_data/dir01"]

The discovered NFS export and SMB shares must have valid underlying filesystem paths. The filesystem directory path must be shared by NFS export, and SMB shares.
